HELP Ryzen MSI B350m Mortar motherboard WILLNOT BOOT

I installed the latest bios update to my MSI B350m mortar motherboard: 7A37v15. After doing so, the computer booted fine, I then went back to the bios to reconfigure the overclock settings. (Ryzen 1600) I believe the frequency was set to 3.8GHz, voltage ~1.38v. (I am pretty sure these were the previous settings). I also set the RAM to one of the XMP presets (preset 1)(this was not a previous setting, I had manually overclocked to ~3000MHz). Then I attempted to reboot, and since then, I have received no signal from the monitor, all of the fans spin up, no debug light on the motherboard. I tried unplugging everything and holding the power & reset buttons. 


Should I consider jumping the CMOS, or maybe removing and replacing the circular battery and trying again? Any ideas welcome.

Clear the CMOS and try again.

Yep this worked, I figured it would, just wanted to avoid relying on this if possible. Now, for some reason, since the bios update, any overclock adjustments made to the CPU in the bios result in this failure to boot issue I had before. I am able to adjust the voltage, and finally have the RAM running at the 3200MHz it was supposed to, but I am unable to tweak the CPU speed in the bios without causing this issue. I can adjust the CPU speed in Ryzen Master from windows, and am able to get slightly faster speeds than before, which is good. But I cannot apply the same settings in the bios for some reason.

 

Any ideas?
